A Review on TiO2 Nanotubes: Influence of Anodization Parameters, Formation Mechanism, Properties, Corrosion Behavior, and Biomedical Applications

Abstract: In this article, influence of anodization parameters on the formation of tubes, tube dimensions, formation mechanism, properties of TiO2 nanotubes (TNT), and their applications in biomedical field are reviewed. The fabrication of TNT of a different shape such as pore size, length, and wall thickness by varying anodization parameters including electrolytes, pH, voltage, electrolyte bath temperature, and current density is examined and discussed. The crystallographic nature of the nanotube obtained by various methods has also been discussed. Finally, the article concludes by examining the key properties including the corrosion aspect and various applications in biomedical field in depth.

Wear and corrosion interactions on titanium in oral environment : literature review

Abstract: The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their surfaces. Additionally, during mastication, micromovements may occur between prosthetic joints causing a relative motion between contacting surfaces, leading to wear. Both processes (wear and corrosion) result in a bio-tribocorrosion system once that occurs in contact with biological tissues and fluids. This review paper is focused on the aspects related to the corrosion and wear behavior of titanium-based structures in the oral environment. Furthermore, the clinical relevance of the oral environment is focused on the harmful effect that acidic substances and biofilms, formed in human saliva, may have on titanium surfaces. In fact, a progressive degradation of titanium by wear and corrosion (tribocorrosion) mechanisms can take place affecting the performance of titanium-based implant and prostheses. Also, the formation of wear debris and metallic ions due to the tribocorrosion phenomena can become toxic for human tissues. This review gathers knowledge from areas like materials sciences, microbiology, and dentistry contributing to a better understanding of bio-tribocorrosion processes in the oral environment.

Mechanical, Moisture Absorption, and Abrasion Resistance Properties of Bamboo–Jute–Glass Fiber Composites

Abstract: Composites have been shown to be commendable alternates to many traditional materials for use in many load-bearing engineering applications. Besides their superior corrosion resistance, composite materials also offer the maximum scope for weight reduction due to their great strength and lower density. In this experimental study, composites of natural fibers (jute and bamboo) and reinforced glass fiber were developed by a hand layup method and their mechanical properties, water absorption resistance, and abrasion responses evaluated as per ASTM standards and compared in dry versus wet conditions. The results show that such use of jute and bamboo fibers with glass fiber-reinforced polymer (GFRP) can result in good mechanical properties, wear resistance, and moisture absorption resistance, representing a good substitute material for GFRP. Composites are generally used in diverse applications including housing, roofing, packaging, automobile industry, etc., and materials such as those described herein could help improve rural economies.

A Green and Sustainable Approach for Mild Steel Acidic Corrosion Inhibition Using Leaves Extract: Experimental and DFT Studies

Abstract: The effect of Holoptelea integrifolia leaf extract (HILE) on corrosive dissolution of mild steel in 1 M hydrochloric acid was investigated using weight loss, surface, electrochemical, and DFT methods. Results showed that corrosion protection capability of HILE increases with increasing its concentration and maximum value of 93.91% was attained at 400 mg/L concentration. Adsorption of phytochemicals present in HILE on metallic surface followed the Langmuir adsorption isotherm. Tafel polarization study revealed that HILE acts as mixed type inhibitor. EIS study revealed that HILE inhibits mild steel corrosion by getting adhered on the mild steel surface. SEM and AFM analyses showed that in presence of HILE, metallic surface becomes smooth because of the formation of inhibitive film over metallic surface. DFT calculations were also performed on the several active phytochemicals. It was found that β-amyrin was the most effective phytochemical for mild steel corrosion among the available constituents present in the extract.

Polymeric-Based Epoxy Cured with a Polyaminoamide as an Anticorrosive Coating for Aluminum 2024-T3 Surface: Experimental Studies Supported by Computational Modeling

Abstract: The present research focused on a coating formulation for aluminum surface 2024-T3 to protect it from corrosion. The formulation consisted of a polymeric epoxy resin-coated bisphenol A diglycidyl ether (DGEBA) cured with a polymeric polyaminoamide. The coated aluminum 2024-T3 was tested in a harsh environment of electrolyte solution (3 wt% NaCl solution) to simulate the harsh marine environment. The coated sample was evaluated by Electrochemical Impedance Spectroscopy (EIS). Under these conditions, a very high impedance (Z) value was obtained; even after exposure for a period longer than 4392 h, the performance was still acceptable. Surface morphological study of metallic specimens before and after exposures to the simulated marine environment (3 wt% NaCl) was carried out using scanning electron microscopy (SEM). The results indicate that the DGEBA-polyaminoamide (DGEBAAA) performed as an excellent barrier for Al surface. The results were combined by several modeling approaches involving molecular dynamics simulation (MD), Monte Carlo methods (MC), and the electronic density functional theory (DFT) computations to explore the adhesion forces between the DGEBAAA and the aluminum surface. The computational MD, MC, and DFT studies were executed in aqueous media. Computational results further evidenced the stronger DGEBA-aminoamide adhesion onto the aluminum 2024-T3 even in a wet environment.
